环境：windows + myeclipse + jdk1.7 + tomcat7 + mysql
代码已经测通，如果有报错可能是我某些地方没描述清楚，请留言。
一、整合原理
二、导包(41个)1.hibernate（1）hibernate/lib/required
（2）hibernate/lib/jpa | java persist api java的持久化规范(接口)
（3）数据库驱动
2.struts2（1）struts-blank.war/web-inf/lib/* 注意:javassist-3.18.1-ga.jar包与hibernate中的重复（只保留高版本即可）
（2）struts整合spring插件包 注意:这个包一旦导入,那么struts2在启动时就会寻找spring容器.找不到将会抛出异常
3.spring（1）基本:4+2 core | beans | context | expression | logging | log4j
（2）整合web:web包 spring-web
（3）整合aop:4个 spring-aop | spring-aspect | aop联盟 | aopweaving
（4）整合hibernate和事务:4个 spring-jdbc | spring-tx | c3p0 | spring-orm
（5）整合junit4测试:test包 spring-test
4.标签库 standard.jar | jstl-1.2.jar
三、单独配置spring容器1.创建applicationcontext.xml,并导入约束(4个) beans | context | aop | tx
<?xml version="1.0" encoding="utf-8"?><beans xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx/spring-tx-4.2.xsd "><bean name="useraction" class="cn.xyp.web.action.useraction"></bean></beans>
2.配置spring随项目启动（web.xml） <!-- 让spring随web启动而创建的监听器 --> <listener> <listener-class>org.springframework.web.context.contextloaderlistener</listener-class> </listener> <!-- 配置spring配置文件位置参数 --> <context-param> <param-name>contextconfiglocation</param-name> <param-value>classpath:applicationcontext.xml</param-value> </context-param>
四、单独配置struts21.配置struts2主配置文件（struts.xml）<?xml version="1.0" encoding="utf-8"?> <!doctype struts public "-//apache software foundation//dtd struts configuration 2.3//en" "http://struts.apache.org/dtds/struts-2.3.dtd"><struts><package name="crm" namespace="/" extends="struts-default"><action name="useraction_*" class="cn.xyp.web.action.useraction" method="{1}"><result name="success">/success.jsp</result></action></package></struts>
2.配置struts2核心过滤器到web.xml <!-- struts2核心过滤器 --> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.strutsprepareandexecutefilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
五、struts2与spring整合1.导包(已经导入) struts2-spring-plugin-2.3.24.jar
2.配置常量 查看默认配置文件从31行开始找到要配置的变量。
### if specified, the default object factory can be overridden here ### note: short-hand notation is supported in some cases, such as spring ### alternatively, you can provide a com.opensymphony.xwork2.objectfactory subclass name here # struts.objectfactory = spring ### specifies the autowiring logic when using the springobjectfactory. ### valid values are: name, type, auto, and constructor (name is the default) struts.objectfactory.spring.autowire = name
添加常量到struts.xml
<!-- # struts.objectfactory = spring 将action的创建交给spring容器 struts.objectfactory.spring.autowire = name spring负责装配action依赖属性--><constant name="struts.objectfactory" value="spring"></constant>
3.整合方案1:struts2自己创建action,spring负责组装依赖属性（了解） <!-- 整合方案1:class属性上仍然配置action的完整类名 struts2仍然创建action,由spring负责组装action中的依赖属性 --><action name="useraction_*" class="cn.xyp.web.action.useraction" method="{1}" ><result name="tohome" type="redirect" >/index.htm</result><result name="error" >/login.jsp</result></action>
不推荐理由:最好由spring完整管理action的生命周期.spring中功能才应用到action上.
4.整合方案2:spring负责创建action以及组装.（推荐） applicationcontext.xml：
<!-- action --><!-- 注意:action对象作用范围一定是多例的.这样才符合struts2架构 --><bean name="useraction" class="cn.itcast.web.action.useraction" scope="prototype" ><property name="userservice" ref="userservice" ></property></bean>
struts.xml：
<!-- 整合方案2:class属性上填写spring中action对象的beanname 完全由spring管理action生命周期,包括action的创建 注意:需要手动组装依赖属性 --><action name="useraction_*" class="useraction" method="{1}" ><result name="tohome" type="redirect" >/index.htm</result><result name="error" >/login.jsp</result></action>
六、单独配置hibernate1.导入实体类&orm元数据
举例：user.java
package cn.xyp.web.domain;import java.util.hashset;import java.util.set;public class user {private long user_id;private string user_code;private string user_name;private string user_password;private character user_state;public long getuser_id() {return user_id; }public void setuser_id(long user_id) {this.user_id = user_id; }public string getuser_code() {return user_code; }public void setuser_code(string user_code) {this.user_code = user_code; }public string getuser_name() {return user_name; }public void setuser_name(string user_name) {this.user_name = user_name; }public string getuser_password() {return user_password; }public void setuser_password(string user_password) {this.user_password = user_password; }public character getuser_state() {return user_state; }public void setuser_state(character user_state) {this.user_state = user_state; } @overridepublic string tostring() {return user [user_id= + user_id + , user_code= + user_code + , user_name= + user_name + , user_password= + user_password + ]; } }
user.hbm.xml：
<?xml version="1.0" encoding="utf-8"?><!doctype hibernate-mapping public "-//hibernate/hibernate mapping dtd 3.0//en" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"><hibernate-mapping package="cn.xyp.domain" ><class name="user" table="sys_user" ><id name="user_id" ><generator class="native"></generator></id><property name="user_code" ></property><property name="user_name" ></property><property name="user_password" ></property><property name="user_state" ></property></class></hibernate-mapping>
2.配置主配置文件（hibernate.xml）<?xml version="1.0" encoding="utf-8"?><!doctype hibernate-configuration public "-//hibernate/hibernate configuration dtd 3.0//en" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"><hibernate-configuration><session-factory> <!-- 数据库驱动 --><property name="hibernate.connection.driver_class">com.mysql.jdbc.driver</property> <!-- 数据库url --><property name="hibernate.connection.url">jdbc:mysql:///crm_32</property> <!-- 数据库连接用户名 --><property name="hibernate.connection.username">root</property> <!-- 数据库连接密码 --><property name="hibernate.connection.password">1234</property><!-- 数据库方言 注意: mysql在选择方言时,请选择最短的方言. --><property name="hibernate.dialect">org.hibernate.dialect.mysqldialect</property> <!-- 将hibernate生成的sql语句打印到控制台 --><property name="hibernate.show_sql">true</property><!-- 将hibernate生成的sql语句格式化(语法缩进) --><property name="hibernate.format_sql">true</property><!-- 自动导出表结构. 自动建表 --><property name="hibernate.hbm2ddl.auto">update</property> <!-- 引入实体配置文件 --><mapping resource="cn/xyp/domain/customer.hbm.xml" /><mapping resource="cn/xypt/domain/linkman.hbm.xml" /><mapping resource="cn/xyp/domain/user.hbm.xml" /></session-factory></hibernate-configuration>
七、spring整合hibernate1.整合原理 将sessionfactory对象交给spring容器管理
2.在spring中配置sessionfactory（1）配置方案一:（了解） <!-- 加载配置方案1:仍然使用外部的hibernate.cfg.xml配置信息 --><bean name="sessionfactory" class="org.springframework.orm.hibernate5.localsessionfactorybean" ><property name="configlocation" value="classpath:hibernate.cfg.xml" ></property></bean>
（2）配置方案二:（推荐） <!-- 加载配置方案2:在spring配置中放置hibernate配置信息 --><bean name="sessionfactory" class="org.springframework.orm.hibernate5.localsessionfactorybean" ><!-- 将连接池注入到sessionfactory, hibernate会通过连接池获得连接 --><property name="datasource" ref="datasource" ></property><!-- 配置hibernate基本信息 --><property name="hibernateproperties"><props><!-- 必选配置 --><prop key="hibernate.connection.driver_class" >com.mysql.jdbc.driver</prop><prop key="hibernate.connection.url" >jdbc:mysql:///crm_32</prop><prop key="hibernate.connection.username" >root</prop><prop key="hibernate.connection.password" >1234</prop> <prop key="hibernate.dialect" >org.hibernate.dialect.mysqldialect</prop><!-- 可选配置 --><prop key="hibernate.show_sql" >true</prop><prop key="hibernate.format_sql" >true</prop><prop key="hibernate.hbm2ddl.auto" >update</prop></props></property><!-- 引入orm元数据,指定orm元数据所在的包路径,spring会自动读取包中的所有配置 --><property name="mappingdirectorylocations" value="classpath:cn/itcast/domain" ></property></bean>
八、spring整合c3p0连接池1.配置db.propertiesjdbc.jdbcurl=jdbc:mysql:///xyp_crm jdbc.driverclass=com.mysql.jdbc.driver jdbc.user=root jdbc.password=123456
2.引入连接池到spring中 <!-- 读取db.properties文件 --><context:property-placeholder location="classpath:db.properties" /><!-- 配置c3p0连接池 --><bean name="datasource" class="com.mchange.v2.c3p0.combopooleddatasource" ><property name="jdbcurl" value="${jdbc.jdbcurl}" ></property><property name="driverclass" value="${jdbc.driverclass}" ></property><property name="user" value="${jdbc.user}" ></property><property name="password" value="${jdbc.password}" ></property></bean>
3.将连接池注入给sessionfactory <bean name="sessionfactory" class="org.springframework.orm.hibernate5.localsessionfactorybean" ><!-- 将连接池注入到sessionfactory, hibernate会通过连接池获得连接 --><property name="datasource" ref="datasource" ></property>
九、spring整合hibernate环境操作数据库1.dao类创建:继承hibernatedaosupport 注意：项目中要确保使用统一版本。
//hibernatedaosupport 为dao注入sessionfactorypublic class userdaoimpl extends hibernatedaosupport implements userdao {
2.hibernate模板的操作（1）execute @overridepublic user getbyusercode(final string usercode) {//hqlreturn gethibernatetemplate().execute(new hibernatecallback<user>() { @overridepublic user doinhibernate(session session) throws hibernateexception { string hql = from user where user_code = ? ; query query = session.createquery(hql); query.setparameter(0, usercode); user user = (user) query.uniqueresult();return user; } });
（2）findbycriteria //criteriadetachedcriteria dc = detachedcriteria.forclass(user.class); dc.add(restrictions.eq(user_code, usercode)); list<user> list = (list<user>) gethibernatetemplate().findbycriteria(dc); if(list != null && list.size()>0){return list.get(0); }else{return null; }
3.spring中配置dao <!-- dao --><bean name="userdao" class="cn.xyp.dao.impl.userdaoimpl" ><!-- 注入sessionfactory --><property name="sessionfactory" ref="sessionfactory"></property></bean>
十、spring的aop事务1.准备工作 <!-- 核心事务管理器 --><bean name="transactionmanager" class="org.springframework.orm.hibernate5.hibernatetransactionmanager" ><property name="sessionfactory" ref="sessionfactory" ></property></bean>
2.xml配置aop事务（1）配置通知
<!-- 配置通知 --><tx:advice id="txadvice" transaction-manager="transactionmanager" > <tx:attributes><tx:method name="save*" isolation="repeatable_read" propagation="required" read-only="false" /> <tx:method name="persist*" isolation="repeatable_read" propagation="required" read-only="false" /> <tx:method name="update*" isolation="repeatable_read" propagation="required" read-only="false" /> <tx:method name="modify*" isolation="repeatable_read" propagation="required" read-only="false" /> <tx:method name="delete*" isolation="repeatable_read" propagation="required" read-only="false" /> <tx:method name="remove*" isolation="repeatable_read" propagation="required" read-only="false" /> <tx:method name="get*" isolation="repeatable_read" propagation="required" read-only="true" /> <tx:method name="find*" isolation="repeatable_read" propagation="required" read-only="true" /> </tx:attributes> </tx:advice>
（2）配置织入
<!-- 配置将通知织入目标对象 配置切点 配置切面 --><aop:config> <aop:pointcut expression="execution(* cn.itcast.service.impl.*serviceimpl.*(..))" id="txpc"/> <aop:advisor advice-ref="txadvice" pointcut-ref="txpc" /> </aop:config>
3.注解配置aop事务（1）开启注解事务 <!-- 开启注解事务 --><tx:annotation-driven transaction-manager="transactionmanager" />
（2）service类中使用注解@transactional(isolation=isolation.repeatable_read,propagation=propagation.required,readonly=true)public class userserviceimpl implements userservice{
@override @transactional(isolation=isolation.repeatable_read,propagation=propagation.required,readonly=false)public void saveuser(user u) { ud.save(u); }
十一、扩大session作用范围1.配置filter 为了避免使用懒加载时出现no-session问题.需要扩大session的作用范围。
<!-- 扩大session作用范围 注意: 任何filter一定要在struts的filter之前调用 因为struts是不会放行的 --> <filter> <filter-name>opensessioninview</filter-name> <filter-class>org.springframework.orm.hibernate5.support.opensessioninviewfilter</filter-class> </filter> <filter-mapping> <filter-name>opensessioninview</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
十二、练习:用户登录1.struts.xml核心配置<struts><!-- # struts.objectfactory = spring 将action的创建交给spring容器 struts.objectfactory.spring.autowire = name spring负责装配action依赖属性--><constant name="struts.objectfactory" value="spring"></constant><package name="crm" namespace="/" extends="struts-default" ><global-exception-mappings><exception-mapping result="error" exception="java.lang.runtimeexception"></exception-mapping></global-exception-mappings> <!-- 整合方案:class属性上填写spring中action对象的beanname 完全由spring管理action生命周期,包括action的创建 注意:需要手动组装依赖属性 --><action name="useraction_*" class="useraction" method="{1}" ><result name="tohome" type="redirect" >/index.htm</result><result name="error" >/login.jsp</result></action></package></struts>
2.action代码public class useraction extends actionsupport implements modeldriven<user> {private user user = new user(); private userservice userservice ; public void setuserservice(userservice userservice) {this.userservice = userservice; } public string login() throws exception { // 1 调用service执行登陆逻辑user u = userservice.getuserbycodepassword(user); // 2 将返回的user对象放入session域actioncontext.getcontext().getsession().put(user, u);// 3 重定向到项目首页return tohome; } @overridepublic user getmodel() {return user; } }
2.service核心代码 public user getuserbycodepassword(user u) { // 1 根据登陆名称查询登陆用户user existu = ud.getbyusercode(u.getuser_code());// 2 判断用户是否存在.不存在=>抛出异常,提示用户名不存在if (existu == null) {throw new runtimeexception(用户名不存在!); } // 3 判断用户密码是否正确=>不正确=>抛出异常,提示密码错误if (!existu.getuser_password().equals(u.getuser_password())) {throw new runtimeexception(密码错误!); } // 4 返回查询到的用户对象return existu; }
3.dao核心代码 public user getbyusercode(final string usercode) { //criteriadetachedcriteria dc = detachedcriteria.forclass(user.class); dc.add(restrictions.eq(user_code, usercode)); list<user> list = (list<user>) gethibernatetemplate().findbycriteria(dc); if(list != null && list.size()>0){return list.get(0); }else{return null; } }
以上就是ssh中三大框架整合详解的详细内容。
